APPARATUS FOR MANUFACTURING FUEL.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Original application filed'December 22. 1903, Serial No. 186,178.Divided and this application filed May 2. 1905. Serial No. 258.474.

T 0 all whom it may concern:

Be it known that I, PAUL HoEniNG, a subject of the King of urtemberg,and a resident of Berlin, in the Kingdom of Prussia, in the GermanEmpire, have invented a certain new and Improved Ap aratus forManufacturing Fuel, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in the manufacture of coke fromaqueous bituminous combustibles, such as peat, brown coal, river-mud,wood and, the like, this application being a division of the applicationfiled by me on the 22nd day of December, 1903, Serial Nr. 186,178, foran improvement in methods of and apparatus for coking hydrou'sbituminousconibustibles.

For carrying out my invention I use continuously working ovens heatedfrom the outside, in which the said combustibles are dried in the firstplace and ridded of the water contained in the same, by the action ofheat and then by the further action of heat converted into coke. Thesteam generated duringthe drying is conducted with any ases formed bythe drying, after the latter ave eventually been superheated, into thehotter parts of the oven. The object of this is to make use of the heatcontained in the steam or the gaseous admixtures and to bring about achemical reaction upon the matters to be gasified, whereby the yield oftar and ammonia is considerably increased. The waste ases can beusediorheating the oven fromt e-outside The invention-is illustratedin theannexed Y dr twings.

Figure 1 shows a vertical section through my improved oven, and Fig. 2is a transverse section on the line 11 of Fig. 1.

The furnace shown in Fig. 1 is fed throughthe shaft or aperture 0 whenthe closing platec has been 0 ened. Through the latter passesa movab ered I) connected with a valve 0. By means of this valve the chambersdand e of the furnace can be placed in communication with each other whendesired;

The preliminary dryingof the .material to be coked takes place in "thechamber (2 from which the material passes to the'chamher e through thevalve 0 which is opened at intervals. In the chamber ethe extraction ofgas and coking of the material takes place. The steam produced by thedrying process in the chamber 'd is conducted downwards .GSS.

through chambers or conduits f to the chamber ewhere it is decomposedinto water-gas which circulates in the coking zone and passes outthrough the conduit {7 together with the gases produced by the cokingproc- The removal of the gases from the chamber 0 is effected by meansof an exhaust fan 9 or'the' like, which conveys the gases through thepipes r and s to other apparatus in which their heat is utilized, orcondensation or other treatment of the gases takes place. In this casethe valve or the slide 2 arranged in the pipe 8, is opened and the valveor slide a, arranged in the pipe 1', is closed. But the valve t being.closed and the valve u being opened the gas exhausted from the chamber(5 is conveyed through the pipe r to a pipe o through which it entersinto the chamber it together with the heating gases generated in anotherlant. In this chamber h-inclosed by the brickwork ackct B, the gases areburned and eil'ect the external heating of the retort A. Theproducts ofcombustion finally escape by an exit w. The air necessary for thecombustion. cf the' gases may enter through an air inlet :0 (preferablyarranged near the 'pipe 1).) It is evident that the heating of theretort A may be erlormed in any other suitable manner without departingfrom the spirit and scope of the invention. The removalot' the materialfrom the chamber e takes lace through the curved conduit 76, in'whichthe inclined slide "L is arran ed. Instead of the chambers f or in combination with them, tubular conduits can be used, arranged outside theretort.

Fig. 2 is a cross section showing conduits jacket B, whic is preferred.v

Having thus described my invention, I claim as new and desire. to secureby Letters 1 Patent:

1. An apparatus for coking aqueous bituminous combustibles, comprising achamher for receiving the combustibles, means for withdrawing gases fromthe lower part of the chamber, means for conducting steam from the u perend of the chamber to the lower end tiiereof, and means for term orarilyseparatin the 'upper part of the c iamber from the Tower part thereof.
